The observatory PHIVOLCS recorded several small phreatic bursts from the Main Crater Lake within the Taal caldera at 11:02 and 17:10 local time today.
The explosive activity was accompanied by emissions of steam-laden plumes, which reached approx. 300-600 meters above the fumarolic vents drifting southwest and northwest. Events were steam driven only, caused by overheated water flashing to steam. Events lasted approx. 4-5 minutes.
Sulfur dioxide (SO2) emissions reached to a 2104 tonnes/day on 18 April.
The seismic station measured 13 earthquakes and five two-minute-long volcanic tremor events over the past 24 hours.
The latest maximum Main Crater Lake temperature reached to a 72.7 °C on 20 February.
The short-term electronic tiltmeter and GPS measurements found the western edifice area deflated. However, from a long-term point of view, instruments continue to register the ongoing uplift of the Taal caldera.
The alert level for the volcano remains at Level 1.
